After running a synchronization with the Zivver Synctool, you see the following error:

Error processing <full_name> (<primary_email>) with status code BadRequest: Error creating alias: Alias is a guest: <alias_email>

Cause

The <alias_email> has already received one or more Zivver messages as a guest recipient. By default, the Synctool does not merge a guest account with the primary Zivver account.

Solution

Enable the Merge guest account into primary account if guest account is an email alias setting under Syncing > Synchronization Options > Special functions (only manual sync), and run a Manual Synchronization.

Note

After the manual synchronization has completed, make sure to disable the setting again.
